10 pages, 10 figures, to appear in the Proceedings of Heavy Quark 8, Southampton, UK, 1999. Version2: This revision fixes a few typos and clarifies one confusing point. No results or physics was changed. Version 3: Corrected typographical errors pointed out by editor of proceedings. Also added first author on exptl. papers instead of listing only the collaboration. Version 4: Didn't get one reference fixed

There has been significant recent experimental activity on the related topics of charm mixing and rare (flavor changing neutral current) decay. For mixing, several new results from direct (wrong sign) searches and first results from lifetime difference (Delta Gamma) searches have been reported. Limits for rmix of approximately 5 x 10-4 (or better) are possible from work in progress. For rare decays, sensitivities to branching ratios are now at the level of a few x 10-6.
